Delivering energy-efficient comfort and operational reliability through expert design, installation and project management.
Background
Cool Services was appointed to replace multiple end-of-life air conditioning systems at Q3 Academy Tipton, a large educational facility in the West Midlands. The site, a multi-level learning and community environment, required an upgraded HVAC solution that would ensure reliable, energy-efficient operation across teaching spaces, offices, and critical IT areas.
The project involved decommissioning, removal, and replacement of several Hitachi VRF (Variable Refrigerant Flow) systems, alongside four single-split systems serving the server room. The client’s key objectives were to improve energy performance, maintain optimal temperature control, and achieve compliance with environmental standards.
The Challenge
The facility’s existing air conditioning systems, installed over a decade earlier, had reached the end of their operational life. Frequent maintenance issues, increased energy consumption, and outdated refrigerant technology meant replacement was essential.
The project’s complexity lay in its scope: multiple system types distributed across two building levels, varied occupancy zones, and a 24/7 operational server room requiring continuous temperature stability. Additionally, the client needed assurance that the new systems would integrate seamlessly with their existing Hitachi control software and comply fully with manufacturer warranty requirements. They also planned the installation with a tight timescale. The summer half term holiday was chosen in order to minimise downtime and disruption to the school’s daily activities.
Our Approach
Cool Services undertook a comprehensive site survey and system assessment to fully understand the facility’s technical and operational needs. Based on these findings, we developed a bespoke solution that balanced efficiency, sustainability and value.
Our proposal included:
- The decommissioning, removal, and safe disposal of the existing Hitachi Level 2 and Level 3 VRF systems and four single split systems, with full environmental compliance and waste transfer certification.
- The supply, installation, and commissioning of new Hitachi Air365 Max VRF Heat Pump systems and R32 Utopia Heat Pump IVX Split Systems, providing reliable heating and cooling performance with advanced inverter technology.
- Integration with the existing Hitachi central controller, ensuring seamless operation across all building zones.
- Full utilisation of existing infrastructure – including refrigerant pipework, interconnecting cables, and condensate drains – reducing both project cost and installation time.
Every phase of the project was managed by an experienced Cool Services project lead, ensuring high standards of workmanship, communication, and health and safety compliance.
System Overview
Server Room Upgrade
The server room’s air conditioning was a critical element of the project. Cool Services decommissioned and replaced four end-of-life wall-mounted split systems with new Hitachi R32 Utopia IVX units, each providing 10kW nominal cooling capacity. Two advanced wired controllers were installed to provide precise temperature control and scheduling flexibility.
The installation reused the existing condensate drains and power supplies, with necessary adaptations made to accommodate the new systems. This efficient reuse minimised disruption to IT operations and allowed the client to maintain uninterrupted cooling throughout the project.
Level 2 and Level 3 VRF Replacement
On Levels 2 and 3, Cool Services removed five ageing VRF condensing units and 20 indoor cassette units, replacing them with new high-performance Hitachi Air365 Max VRF systems.
The new systems deliver improved seasonal energy efficiency ratios (SEER) and coefficient of performance (COP) values compared to the previous models. Indoor units ranged in capacity from 7.1kW to 14kW, providing tailored comfort control for a variety of room sizes and occupancy levels.
All installations were carried out in the same positions as the original equipment, reducing the need for extensive structural adaptations. Once installed, each system was pressure tested, evacuated, and commissioned in accordance with Hitachi’s manufacturer standards.
Commitment to Quality and Compliance
At Cool Services, every project is delivered under our strict quality management processes, ensuring client confidence and system longevity.
Our engineers are manufacturer-trained and equipped with the latest safety tools and equipment. We maintain clean, organised working environments throughout the installation process and follow all site-specific health and safety procedures.
The project also included a crane lift, waste disposal, and electrical adaptations, all managed within the agreed timescale and budget. A full commissioning report and manufacturer documentation were provided upon completion, guaranteeing that the client could take full advantage of Hitachi’s 12-month parts and labour warranty, extendable to five years with ongoing maintenance from Cool Services.
Client Benefits
This installation provided the client with a number of measurable advantages:
- Energy Efficiency: The new inverter-driven VRF systems modulate compressor speeds based on demand, significantly reducing energy consumption and operating costs.
- Sustainability: Upgrading to R32 refrigerant where possible and retaining serviceable pipework reduced environmental impact and installation waste.
- Cost Control: Reuse of existing infrastructure and integrated system design minimised both capital expenditure and downtime.
- Reliability: Modern Hitachi systems provide consistent temperature regulation, essential for maintaining comfort in learning environments and protecting sensitive server equipment.
- Warranty Assurance: Compliance with manufacturer standards and Cool Services’ maintenance support ensures long-term warranty protection and system reliability.
Ongoing Partnership
Cool Services’ relationship with the client extends beyond installation. As part of our aftercare programme, we offer scheduled maintenance and support to ensure continued efficiency, reliability and compliance with warranty requirements.
